Not exactly. Many people feel their best wehn their TSH is in that range, BUT....
The best bet is to get Free T4 in the middle of the upper half of its range, regardless of TSH. A fairly recent study showed that pregnancy ws better supported and healthier babies (physically, and especially mentally) were born to mothers whose Free T4 was in the middel of the upper half of the lab range and kept there.
This is ESPECIALLY crucial in the first trimester before the baby has its own thyroid gland developed and most of the crucial parts of the brain and nervous system are forming. Later in the pregnancy, it is still important, but the baby will provide its own thyroid hormones as needed.
